We Should Be Able To Detect Spaceships Moving Near The Speed Of Light

A pair of engineers say it's possible to detect the signatures of spacecraft traveling at relativistic speeds, and we can do so using current technologies. The trouble is, their new analysis also suggests that moving through space at ludicrous speed is more hazardous than previously thought. » 3/25/15 8:40am 3/25/15 8:40am

The Planck Satellite Discovers Extra Dark Matter In the Universe

This week, the Planck Satellite team announced major findings from over a year of observations of the Cosmic Microwave Background (CMB), or the radioactive sludge that lingers in our universe from the beginning of time, right after the Big Bang. And while there's a lot to digest, I wanted to give you some high… » 3/22/13 7:00am 3/22/13 7:00am

Does our solar system have a special connection to the structure of the universe?

For the past five hundred years, we've been looking out at the universe and assuming that we, with our little planet and our little solar system, were nothing special. And then we sent out a probe to measure the cosmic microwave background. It gave us some data that makes it seem like we might be a bigger deal than… » 3/07/13 12:49pm 3/07/13 12:49pm
